Ok, I have 3 word problems dealing with probability that I need help with. So here they areWondering)
1.Suppose a contest offers $1,000 to the person who can guess the winning 4 digit number. How many possibilities are there?
2. Two marbles are drawn froma bag containing 6 white, 4 red, and 6 green marbles. Find the probability of both marbles being white.
3. Suppose there are 10 items on a true-false test. The person taking the test does not read the questions; he just answers each question randomly. What is the probability of his guessing all answers correctly?
Thanks in advance for any help!
